Examples with SingletonScope org.eclipse.xtext.scoping.impl.SingletonScope used on opensource projects

Example 1 with SingletonScope

use of org.eclipse.xtext.scoping.impl.SingletonScope in project xtext-extras by eclipse.

the class SerializerScopeProvider method createFeatureCallSerializationScope.

// TODO split this into smaller methods, investigate override / overload semantics
// This assumes that the model was linked properly and not changed in an incompatible way
// which is quite hard anyway ...
public IScope createFeatureCallSerializationScope(EObject context) {
    if (!(context instanceof XAbstractFeatureCall)) {
        return IScope.NULLSCOPE;
    }
    XAbstractFeatureCall call = (XAbstractFeatureCall) context;
    JvmIdentifiableElement feature = call.getFeature();
    // this and super - logical container aware FeatureScopes
    if (feature instanceof JvmType) {
        return getTypeScope(call, (JvmType) feature);
    }
    if (feature instanceof JvmConstructor) {
        return getThisOrSuperScope(call, (JvmConstructor) feature);
    }
    if (feature instanceof JvmExecutable) {
        return getExecutableScope(call, feature);
    }
    if (feature instanceof JvmFormalParameter || feature instanceof JvmField || feature instanceof XVariableDeclaration || feature instanceof XSwitchExpression) {
        return new SingletonScope(EObjectDescription.create(feature.getSimpleName(), feature), IScope.NULLSCOPE);
    }
    return IScope.NULLSCOPE;
}

                int dot = qualifiedName.lastIndexOf('.');
                String simpleName = qualifiedName.substring(dot + 1);
                return new SingletonScope(EObjectDescription.create(simpleName, type), IScope.NULLSCOPE);
